SPECIFICATION forming 'part of Letters Patent No. 783,834, dated February 28, 1905.

Application filed May 26, 1904. Serial No. 209,839.

To a, who/11 lit-Hwy cone/17%:

Be it known that 1, JOHN F. HAYns, a citizen of the United States, residing at Richmond, in the county of ltlenrico, State of Virginia, have invented certain new and useful Improvements in Oven- Dampers for Ranges, of which the following is a specification, reference be ing had therein to the accompanying drawings, in which-- Figure l is a perspective view of the damper; Fig. 2., a rear view thereof; Fig. 3, a vertical sectional view on the line 3 3 of Fig. 2; Fig. i, a detail perspective view of one end of the damper-plate; Fig. 5, an end view of the same end of the damper; Fig. 6, a bottom view thereof; Fig. 7, a vertical sectional view of a stove,showing the damper in position; and Fig. 8, a detail horizontal sectional view showing more clearly the position of the damper and damper-rod in the stove.

One of the many objects of the invention is to provide a damper which may be placed in position in a range or removed therefrom r aadily and. without removing any portion of the range, except, of course, the usual pothole lids.

Another object of the invention is to provide an oven-damper of such construction that the damper-rod will be placed near to or against the vertical end of the stove opposite the iire-box and away from the top of the oven, so that it will not form an obstruction on the top of the even, as is the case with the ordinary dampers now in use, and will not become unduly heated, it being out of the direct line of draft around the oven.

Other and equally important objects and advantages of the invention will appear hereinafter.

Referring to the various parts by numerals, l designates thedamper-plate, which is located in the usual position at the back of the stove or range and is adapted when in one of its positions to cause the products of combustion or draft to pass around the oven before entering the smoke-pipe and in its other position to permit the products of combustion to pass directly into the flue. This damper-plate is formed on its forward side near its upper edge with a longitudinal rib 2, and at its lower lefthand corner it is formed with a pivot-lug or journal 3. The right-hand end of the damper-plate, at the lower corner thereof, is cut out, as at 4 in Figs. 2 and a, and on its rear .s'ide adjacent such cut-out portion it is formed with a rearward-extemling horizontal flange or rib 5. At its lower edge it is formed with a rearward-extemling longitudinal flange 6, said flange extending from a point directly below the inner end of the lug to the lefthand end of thedamper-plate. The rib 2 and flange 6 brace the damper-plate and prevent it being distorted by heat.

Securely bolted to the rear side of the damper-plate is a crank-carrying plate 7, whose outer end projects boyoml the right-hand end of the damper-plate and forms a journal 8, which is adapted to enter a recess in the adjacent wall of the range to support one end of said plate. The upper edge of this crankcarrying plate, near the inner end thereof, lits squarely against the under side of the short rib or lug 5, while its inner end abuts closely against the adjacent end of the flange 6, the lower edge of this plate being flush with the lower edge of the [flange 6 and the lower edge of the dam 'ier- 'ilate, as shown clearly in Figs. 2 and l. Formed integral with the crank-carrying plate 7, at the inner end of the journal 8 thereof, a forward and upward extending crank-arm 9, which at its upper end is formed with an outward-extemling horizontal pivot-lug 10. This crank-plate is rigidly secured in position by means of a stove-bolt 11, and the crank 9 extends forward through the cut-out part at. bears against a boss 15 on the front side of the damper-plate.

The damper-rod 12 is pivoted at its inner end on the pivot-1ug 10 of the crank-arm, said damper-arm being placed on its edge to adapt it to lie close to or against the vertical wall of the range at the greatest distance possible from the lire-box and out of the vertical plane of the oven. The free end of this damper-rod is provided with the handle 13, which projects through the front wall of the range. From the foregoing it will be readily seen that the The nut on the bolt 11.

l damper-rod will not lie on the top of the oven and will be out of the draft around the oven. By placing the operating rod practically against the side wall of the range it will be beyond the oven-door, so that any dust or ashes drawn through the front wall by it will not drop on the oven-door or into the oven. It is clear that this damper-rod will not become so highly heated as the rods which are mounted to slide on the top of the oven.

By removing the bolt 11 the crank-carrying plate may be detached from the damper-plate to permit the entire device to be readily removed from the range or placed therein.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. An oven-damper for ranges comprising, a damper-plate formed with a journal at one lower corner, a crank-platedetachably secured thereto at its other lower corner, a journal formed on said crank-carrying plate, an upward and forward inclined crank-arm formed on said plate at the inner end of the journal, and an operating-rod adapted to be connected to the upper forward end of the crank.

2. An oven-damper for ranges comprising, a damper-plate provided with a permanent journal at one end, a crank-carrying plate detachably secured to the rear end of the damper-plate at the other end thereof and formed with a journal at its outer end, a forward and upward extending crank formed on said crankcarrying plate, rearward-extending projections on the damper-plate adapted to engage the crank-carrying plate to prevent the rotation thereof, an operatingrod extending through the front wall of the range and connected to the upper forward end of the crank.

3. In an oven-damper for ranges the combination of a range, a damper-plate formed with a journal at its inner lower corner, a crankplate detachably secured thereto at its outer lower corner, a journal formed on the outer end of said crank-plate, supports in the range for said journals, an upward and forward inclined crank-arm formed on said crank-plate at the inner end of thejournal, said arm lying close to the side of the range, an operatingrod connected to said crank and lying close to the side of the range, whereby said rod may be placed out of the vertical plane of the oven, substantially as described. 7

In testimony whereof I hereunto afliX my signature, in the presence of two witnesses, this 20th day of May, 1904:-

JOHN F. HAYES.
